May grow to 40mm long, and have relatively long oral tentacles growing to about half the body length. The rhinophores are smooth and taper to a blunt tip. The body is translucent clear with some orange pigmentation especially in larger animals. opaque white specks are scattered over the head and oral tentacles and on the tips of the tentcales and the rhinophores. There is often a large white patch between the rhinophore bases. The cerata also have white patches and a whitish tip. Thompson & Brown (1984) report it feeding on Tubularia larynx in southwestern Ireland.
